2004 Freightliner Sprinter 3500 Glow Plugs

Relays are electrical switches used to convert a small electrical load into a circuit capable of handling a high amperage load. Computers and small switches are not designed to carry the higher amperage requirement of a circuit that may have an electric motor, solenoid, or high amperage lighting fixture. Within a relay are contacts that are controlled with electromagnetism, when the circuit switch commands the device on or off, magnetism will pull or release the contact arm closing or opening the contacts within the relay that carry the voltage.

Product Features:

• Product constructed to meet all design and operating characteristics as intended by the vehicle manufacturer.
• Computer-Aided Design (CAD), laser scanning and 3D printing – utilizing Fused Deposition Modeling (FDM) and Stereolithography (SLA) – in the part design process ensures speed-to-market and a precise fit guaranteed.
• Where applicable, robust circuit board design increases durability due to heat, shock, and random electro-magnetic pulses (EMP) and power spikes.
• Tin plated lead frame prevents corrosion and ensures a reliable terminal connection under adverse ambient conditions.
• 100% thermo-shock and vibration tested to ensure superior performance in extreme conditions.
• 100% end-of-line tested to ensure accurate signal output providing product reliability, every time.

NGK’s patented NHTC (New High Temperature Ceramic) glow plugs were developed for OEM diesel engine manufacturers to comply with ever-stricter emissions standards. Compared to metal glow plugs, NHTC glow plugs have a more robust, fully ceramic heating element which is encased in a ceramic insulator. NGK NHTC glow plugs reach operating temp of 1000 degrees Celsius in less than 2 seconds and can after-glow for more than 10 minutes at temps of up to 1350 degrees Celsius. Silicon nitrate ceramic material, combined with optimized shape and joining process provide superior thermal shock and vibration resistance, ensuring stable engine starts. Fine ceramic heater provides durability in high-temperature conditions, improves combustion and reduces emissions.

Product Features:

• ACTUAL OE or EQUIVALENT DESIGN: OEM quality construction ceramic glow plug
• PATENTED TECHNOLOGY: Exclusive NHTC New Ceramic High Temperature design
• NEAR-INSTANT HEATING: Fully ceramic heating element reaches operating temperature in less than two seconds
• CLEAN PERFORMANCE: Constant afterglow temperature minimize noxious pollutants
• RECOMMENDED USAGE: Best for diesel engines with OE ceramic glow plugs

NGK metal glow plugs are trusted by OEM diesel engine manufacturers around the world to perform under the harshest conditions. NGK metal glow plugs are equipped with a heating coil in a glow rod made of heat-resistant magnesium oxide between the heating and regulating coils. Magnesium oxide is an outstanding thermal conductor (quickly dissipating heat), while protecting the heating coils from vibration and shock. NGK metal glow plugs feature excellent gas-tight sealing qualities that deliver superior electrical insulation and protection against combustion gas. NGKs metal composition helps reduce carbon accumulation to prevent short circuits, while the unique shell design provides excellent heat transfer.

Product Features:

• ACTUAL OE or EQUIVALENT DESIGN: OEM quality construction metal glow plug
• SUPERIOR DURABILITY: Metal glow plugs are designed to withstand thermal shock due to quick changes in temperature
• FAST HEATING PERFORMANCE: Fast heat up enables smooth engine starts even in extreme weather conditions
• CLEAN PERFORMANCE: Constant afterglow temperature minimize noxious pollutants
• RECOMMENDED USAGE: Best for diesel engines with OE metal glow plugs
